Abstract

We propose a joint model for POS tagging and dependency parsing. Our model consists of a BiLSTM-CNN-CRF-based POS tagger [26] and a Deep Biaffine Attention-based dependency parser [24]. A combined objective function is used to jointly train both models. Experiment results show very competitive performance on several languages of the Universal Dependencies (UD) v2.2 Treebanks [11].
